RADIATOR.

Specification of Letters Patent.

Patented Aug. 6, 1918.

To all whom it may concern:

Be it known that I, JOHN M. Frzoonns, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to that class of radiators which are more particularly designed for cooling the water of gas engines and has for its object the provision of means whereby this can-be accomplished economically and efficiently and in a manner which will increase the strength of the radiator and also permit the same to be manufactured expeditiously by the employment of comparatively unskilled help.

In the accompanying drawings: Figure 1 is a fragmentary front view, partly in section of a radiator core constructed in accordance with my invention. Fig. 2 is a horizontal section taken on line 22 Fig.

1. Flg. 3 is a perspective "iew of one of the radiatin members or sections interposed between ad acent water tubes of the radiator.

Similar characters of reference refer to like parts throughout the several views.

1 represents a plurality of water tubes or passages which are arranged side by side and which are adapted to be connected at their opposite finds with the water circulating system of the gas engine for the purpose of reducing the temperature of the water and cooling the/engine accordingly. Each of these water tubes is constructed of two strips 2, 2 of sheet metal which are bent into corrugated form which strips are so assemform opposite walls of a tube and are providedat their corresponding longitudinal edges with ofl-sets 3 which are connected with each other by solder or other suitable means. A plurality of such tubes are arranged side by side so that adjacent water tubes are spaced apart and the valleys or bottoms of the corrugations on the eXterior of one tube wall are arranged transversely in line or opposite to the external valleys or bottoms of the opposing wall of an adjacent tube.

Between ev ry two adjacent Water tubes is arranged a p urality of radiating members or sections which operate to dissipate the heat of the tube walls to the atmosphere. Each of these radmting, members comprises a longitudinal web 4 and two transverse flanges 5, 5 arranged at oppositeside edges of the web, one of these flanges being arranged at rightangles to this web and projecting laterally therefrom in one direction while the other flange is also arranged at right angles to the web and projects laterally therefrom in the opposite direction so that this web and these two flanges together are of substantially Z-shaped form in cross section. At suitable intervals the web of each of these radiating members is provided with retaining lips 6 which are struck out of the stock of this web, some of these lips being bent and formed so that they pro ect from one side of this web opposite to one of the flan es and are arranged in line therewith whi e others of these lips prject from the other side of this web and in an opposite direction from the other flange, but in line with the latter. The web, flanges and lips of' each radiating member are preferably constructed integrally from a single sheet of metal by means of suitable dies.

In assembling the radiating members, a plurality of the same are arranged in a longitudinal row between two opposing walls of a pair of adjacent water tubes so that the flange and lips at one side edge of each Web engage fiatwise with the lips and flanges at one side edge of an adjacent radiating member, and the outer edges of these lips and flanges engage with the of corresponding corrugations of adjacent water tube walls. sembled the several webs of a set or group of radiating members between .two water tubes are arranged lengthwise in line and these radiating members together with these tube walls form two longitudinal rows of air passages 7 through which the air passes from one side of radiator to the other for the purpose of carrying away the heat from the tube walls and the radiating members. These radiating members are retained in place between the tube walls referably by soldering opposite ends thereo to the walls. By thus constructing each radiating memher, the same forms an efiicient means for aiding in cooling the water and it also effectively braces the water tubes relativel to each other so that the radiator as a who e is very strong.

a pair of When thus as- Owing to the simplicity of this construc-' valleys or bottoms bled by persons having little skill without liability of inisplacing the parts or nnpalring the elliciency or strength of the radiator.

By this formation of the retaining lips on each radiating section the same when placed nor added cost is incurred.

Furthermore, the openings 8 which are formed in the web by striking out the retaining lips therefrom provide means for permittin a cross circulation of the air in the radiating core and thereby equalizing the radiating eliiciency of the same.

I claim as my invention:

l. A radiator comprising a plurality of water tubes one wall of each tube being ar-- ranged opposite and spaced apart from a wall of an adjacent. tube, and a radiating member arranged between adjacent tubes and having a longitudinal web, a flange arranged at one side edge of the weband projecting laterally therefrom in one'direction into engagement with one wall of one of said tubes, another flange arranged on the other side edge of said web and projecting laterally therefrom in the opposite direction into engagement with one wall of another tube, and retaining lips projecting in opposite directions from said web into cnga ement with the opposing walls of two ad acent water tubes.

2. A radiator comprising a plurality of water tubes, one wall of each tube being ar ranged opposite and spaced apart from a wall of an adjacent tube, and a radiating member arranged between adjacent tubes and having a, longitudinal web, a flange ar ranged at one side edge of the web and projecting laterally therefrom in one direction in engagement with one wall of one of said tubes, another flange arranged at the other side edge of said web and projecting laterally therefrom in the opposite direction into engagement with one wall of anotl'ier tube, and retaining lips struck out of said web and projecting in opposite directions there from into engagement with the opposing walls of two adjacent water tubes.

3. A radiator comprising a plurality of water tubes, one wall of each tube being arranged opposite and spaced apart from a. wall of an adjacent tube, and a radiating member arranged between adjacent tubes and having a longitudinal web, a flange arranged at one side edge of the web and projecting laterally therefrom in one direction in engagement with one wall of one of said tube another flange arranged at the other side edg'. of said web and projecting later-- all y therefrom in the opposite direction into engagement with one wall of another tube,

and retaining lips struck out of said Web and arranged in line with said flanges, respectively, and projecting in opposite d1reclions into engagement with the opposing walls of two adjacent water tubes.
